Question

 The Oval Office, _____ in the White House, is the office of the President of the United States.

(a) was situated

(b) is situated

(c) situated

(d)situate

Answer 1

The correct answer is: c. situated. This is an example of a nonrestrictive clause offset by the commas after "Office" and "House." It provides nonessential information, can be removed from the sentence without changing the sentence's meaning, and cannot stand on its own as a sentence. Also, the use of "situated" here is as an adjective, not a verb; all other answer choices are verbs.
